This vulnerability allows for information disclosure in the Azure Command-Line Interface (CLI) through REST commands. With a CVSS score of 8.6, this high-severity vulnerability poses a significant threat to organizations that utilize Microsoft Azure services. The vulnerability can be exploited over a network with low complexity and without requiring any user interaction, making it particularly concerning.
Risk to organizations includes unauthorized access to sensitive information, which can lead to data breaches or other malicious activities. As this vulnerability has not been identified as actively exploited in the wild, organizations should still prioritize remediation to safeguard their assets.
Organizations should prioritize patching immediately. The prompt application of security updates is crucial to mitigate the risks associated with this vulnerability.
The vulnerability was disclosed on November 14, 2023. As Microsoft's security advisory indicates, it is critical for users of the Azure CLI to monitor for updates and apply necessary patches as they become available.
Vulnerability Details
The Azure CLI REST Command Information Disclosure Vulnerability is classified under CWE-359. The CVSS 3.1 vector string for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N, reflecting a network attack vector with low complexity, no privileges required, and no user interaction necessary.
Affected products include the Azure Command-Line Interface, specifically versions prior to 2.53.1. Organizations utilizing versions in this range should take immediate action to secure their environments.
Technical Analysis
The root cause of this vulnerability stems from improper handling of REST command responses in the Azure CLI, allowing sensitive data to be disclosed. The attack vector is network-based, meaning an attacker can exploit this vulnerability remotely. The complexity of the attack is low, as no specific technical skills are required to initiate exploitation. Importantly, no privileges are required for exploitation, and there is no need for user interaction.
The confidentiality impact is rated as high, indicating that exploitation can lead to significant data exposure. In contrast, integrity and availability impacts are rated as none, meaning that exploitation does not affect the integrity or availability of the system.
Risk & Impact Analysis
Real-world deployment risk is substantial given the high confidentiality impact. Organizations that rely on Azure services must recognize the potential for sensitive information to be exposed, leading to data breaches and compliance violations. The urgency for remediation is underscored by the CVSS score, which classifies this vulnerability as high severity.
Organizations should address this vulnerability in their priority patch cycle to minimize the risk of exploitation. Given that the vulnerability is not currently known to be exploited in the wild, organizations still need to maintain vigilance and ensure that all systems are patched promptly.
